Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990412, here are decompositions:

23 + 990389 = 990412
29 + 990383 = 990412
41 + 990371 = 990412
53 + 990359 = 990412
83 + 990329 = 990412
89 + 990323 = 990412
131 + 990281 = 990412
173 + 990239 = 990412

Showing the first eight; more decompositions exist.
